Oil in exhaust manifold
Don't know why w have oil in the exhaust
manifold. Replaced the fuel pressure
regulator thinking it was that and nothing.
Now have white smoke coming from
exhaust pipe that smells like oil. This is in
my 2000 yukon denali 5.7. Please someone
help don't know what else to do.
Oil in exhaust? Normally this will create blue smoke. Sounds more like a busted up head gasket or possible intake gasket, creating white smoke from being ignited in the engine then passing this fog/steam out the exhaust, this moisture is then collecting on the internal sides of the exhaust system basically steam cleaning the pipes ans the end result is black or dark fluid exiting the pipes, This is not good for your Catalytic converter BTY. The smell is anti-freeze.
Ok thank you helps out alot. Appreciate it
